尖端扭转型室速(TDP)是介于室速与室颤之间的一种恶性心律失常。它是由法国学者De-ssertenne氏于1966年首先提出的,随着心脏监护仪器及动态心电图的广泛应用,其在临床上已不属罕见。1.病因:近来多数学者主张Q-T间期延长是诊断扭转型室速的必要条件,而Q-T间期的延长系指Q-Tc>0.44秒,可分为原发性和继发性两种类型。原发性Q-T间期延长又可分为三型,即①Jervell-Lange-Nielsen综合征;患者均有家族
Torsades de pointes (TDP) is a malignant arrhythmia between VT and ventricular fibrillation. It was first proposed by the French scholar De-ssertenne in 1966, and with the widespread use of cardiac monitoring instruments and Holter, it has not been clinically uncommon. 1. Etiology: Recently, most scholars advocate prolongation of QT is a necessary condition for the diagnosis of torsades de pointes, and QT prolongation means Q-Tc> 0.44 seconds, can be divided into two types of primary and secondary . Primary Q-T prolongation can be divided into three types, namely: ① Jervell-Lange-Nielsen syndrome; patients have a family
